I may be filming several live open mic shows Its one camera, using sony z1 - i have the Sennheiser EW100-ENG G3 kit so i have a senn. camera receiver. Would this pick up the wireless mic audio from the singer's wireless mic on stage? - would this mess up the pa system, ie can two receivers pick up the audio at the same time. i assume you can because its just a radio transmitter? If theres more than one singer, would all mics be broadcasting on the same frequency? I have a rode ntg2 so perhaps stick this near the stage with plug on transmitter - where would be the best place to put this - ie side on / front on? (on a mic stand) this would effectively get any guitar / drum players etc... or multiple singers.
